Application filed February To all whom it mag concern Be it known thatI, FRANKS. E'enorr, a citizen of the United States, residing atRiverside, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements "in ,Oil Burners, of which thefollowing is a specification This invention which relates to an oilburner is designed particularly for use with building heating'plants ofvarious kinds. In its construction are embodied numerous features ofimprovement having to do with simplicity in the construction andassembly. of its several components, and with general accessibility orremovability of its princ pal units for purposes of repair, replacgment,

. burner showing the interrelation of its several components; and.

Fig. 2 is a plan view thereof with the flame andring deflectors removed.

The presentburner comprises four ma'or -unitsa burnerl'iead A- whereonis rest-e a flame deflector B, a frame C in which the burner ,head. ismounted, and a ring D ,loosely carried; in the frame. These severalparts, when assembled as shown in Fig.- 1, are adapted to be placedwithin a" furnace wherein pipe connections are also carried to supply orremove oil as required.

The burner head is in the general form of a hollow cone having an innercylindrical wall 3 uniting with a. bottom A which, in turn, is unitedwith the lower, edge of an outer cone wall 5 having its -upper edgeterminating, by preference, slightly below the upper edge of thecylindrical wallB. Between the upper edge of the cone wall 5 and thecylindrical wall 3 is an opening 6, shown as annular, communicating withthe chamber 7 which is formed interiorly of the burner head by the wallsand bottom just described. A fuel inlet pipe 8 is connected definitelyadvantageous FRANK S. EGLOFF, OF RIVERSIDE, ILLINOIS.

.A drain pipe 13 connects with the trough,

.as shown. An undercut shoulder 14 is-fur- -ther formed on theperipheral wall, 'and incomplementary relation thereto are certain webs15 projecting.inwardly from .the frame C. This frame which is ofplate-likestructure provides through themedium of its several webs aseatinwhich theburner head is rested, a plurality of arc-shaped openings 16having a substantial area intervening therebetween. Each of these webs,as shown.

is provided-with a lug 17 adapted to engage '80 i with the under side ofthe shoulder-14 to thereby afford support for the burner head-i.

By rotating the head to the position shown in Fig. 2 the cam ribs, willbe caused to engage with certain grooves 18 that are provided in thewebs so as to interlock the head with the. frame. Manifestly the headmay- 'be removed "after being turned in a reverse direction suflicientlyto disengage the cam ribs from thewebs of the frame. I

An upstanding shoulder 19 is provided on the frame in such a manner asto form an annular seat"whereon the ring D may be ,loosely rest-ed. Thewalls of this ring, ac-

Forconvenience in handling, an eye 23 is provided on-the upper w I side ofthe deflector, as shown. An e11 burner answering to the above ,de-

being fixedly secured in place therewithin.

Adjacent the out-er periphery of the frame I have provided severalelongated arcuate slots 24: through which, at any point'intermediate oftheir ends, one or more attaching bolts (not shown) may. be inserted forsecuring purposes. Manifestly the ring D may be lifted o'fi'of its seatwithout any preliminary operation. whenever its removal is desireLikewise the flamedefiector maybe taken off of the burner head byasimilar'operation. By first unlocking the burner'h'ead through a rotary1noti0n, it may be removed' from'. the frame, either through 1ts upperor lower' side. .Incarrying out this latter operation, it iscontemplated that the two oil pipes should be disconnected, preferablyat the union (not. shown) which, in ordinary prac'' tice, is locatedclose. to the. furnace door.

The present burner may use advantageous' lyany suitable distillate Whosegravity range is, say, from 36 to 42 degrees Bau'm. The chamber 7 isfilled from the supply pipe so that the oil thereinmay burn at 'theopening 6, the oil burning' at that point only; producing the minimum.amount of flame and heat. WVith i crease in the flow. of oil to theburner, a portion of the fuel which overflows upon the relativelysteepconical walls 5 will spread and breakup, thelighter partbeing consumedbefore; reaching the base of the cone; vthe flow of the heavier portionof the fuel is retarded atthe shoulder of the cone, being consumed atthatpoint or above sofas to produce the maximum amount of flame'andheat, the flame being spread in a desirable manner by meansofthedeflector- B.

In case any valve controlling the flow. of oil through the intake pipeis opened accidentally or otherwise, so as to allow oil to.

flow through the burner without being ignited,,or in case of an excessof-oilbemgfed to the burner, any such excess or overflow is collected atthe trough 10- from -whence it flows through the'o'utlet pipei13 into acup (not shown) which may operate :a drip valve for shutting o'fl the,oil passing through the supply pipe.
